CRUDE-OIL BURNER.

Specification'of Letters Patent. Patented Fem- 22 1910 Application filedMay 24, 1909. semi No. 497,837.

To all whom it may concern:

Be it known that I, FREDERICK IV. LANOIX,

acitizen of the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Crude-Oil Burners, of which the following is aspecification; My invention relates to improvements in crude-oilburners,,and one of my objects is to provide a simple and eflicientburner of this character.

l/Vith the above and other objects in view, the invention may be said toconsist in the novel construction, combination, and arrangement of partshereinafter described,

' illustrated in the accompanying drawing,

and pointed out in the claims appendedhereto, it being understood thatvarious changes in form, proportions, and minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of the ins vention. Referring now to said drawing:Figure 1 represents a vertical central section of the burner on line I-Iof Fi 2 Fig. 2 is a horizontal section on line IL-II of Fig. 1. Fig. 3is a broken, inverted plan view. Fig. 4 is an inverted perspective viewof a disk employed in carrying out the invention.

In carryingout the invention,-'I employ a hollow cup-shaped casting 1,comprising an inner wall 2 and an outer wall 3,

' spaced apart to form an air-chamber 4:.

The bottom portion of the outer wall 3 has a central opening 5 formingan inlet to chamber 4, and the upper portion of the inner wall 2 has anannular row of holes 6 forming an outlet from said. a1r-chamber.

The bottom portion of the inner wall 2has a central depending nipple '7'threaded so that itmay be connected to a supply-pipe, not shown.

, 8 designates a reinforcing member which is screwed upon the nipple tosecure the same and the bottom of the outer wall together.

9. designates a sheet-metal pan fitting within the inner wall from whichit is spaced to form' a second air-chamber 10,

having communication with the air-chain her 4 through the holes 6. Pan 9is pro-v vided at its upper end with an annular flange 11 which restsupon the upper. sur

face of the outer wall,'and said pan is held centrally within the innerwall 2 by a plurality of spacing lugs 12 integral with the upper'portion of said inner wall. 'lan .9

has a central opening 13 in its bottom porerable distance to cause theflame to impinge against the bottom and side of the pan.

In practice oil is admitted to the bottom of the inner wall 2 andignited. The flame thus produced passes upward through 0 en-- ings 13,where it is spread against the interior' of the pan by the disk-14. Thisheats the air in the chambers 4 and 10 and causes it to flow'outwardthrough opening 13 and draw in a fresh supply through inlet 5. j Astheheatedsair esca es through opening 13 it becomes thcrou 1y intermixedwith the flamepsupplying te same with sufiiciently heated 0 gen toinsure complete combustion of ithe fuel- A small portion of the flamewlll also escape through opening 1? but as the same is small, comparedto the annular,opening"18 between the pan and theedge of the disk, thegreater portion of the flame will escape through said annular opening,and inimpinging against the pan sup'erheat the air in chain er 10.

Having thus described my invention, what I claim 1s: p t

1.; An oil burner consisting of a hollow cup-shaped c'astin comprisingan outer wall and-an inner wal forming an air-chamber with inlet andoutlet openings in said walls, oil-supplying- -means communicating withthe bottomofthe inner wall, a pan fitting within theinner wall andspaced therefrom to form a-second air-chamber having an outlet throughthe bottom of the pan and communicatin 'with the first-mentionedairchamber-tIirough the outlet thereof, and a disk'spaced' above thebottom of the pan,

substantially as described. 2. An oil burner consisting of a .hollowcup-shaped casting comprising an outer wall and an inner wall forming anaiz chamber with inlet and outlet openings in said walls,

a nipple depending from the inner wall through the inlet opening in theouter wall, reinforcing means ugagmg the nipple and the, bottom of theouter wall, a pan removably fittingwithiii the inner wall and spacedtherefrom to form a second air-chamber having an outlet through thebottom o;t the r pan and communicating with the first-men- 1 tionedair-chamber; through the outlet thereof, an annularfiange carrying saidpan and supported bythe upper portion of the cupshaped casting, meansextending inwardly 15 opening in the bottom. of the pan, said disk 20being provided with lugs whereby it is .supported above the bottom ofthe pan.

In testimony whereof I affix my signature,

, in the presence of two witnesses.
